Be it known that I, RorH. SMITH, a. citizen of the United States, residing at Kent, in the county of Portage and State of Ohio, have invented a certain new and useful Improvement in vMethods of :lfifilaks ing Tools, of: which the following is a full,

This invention relates to a method of malt.- ing tools, and has particular referenceto the manutacture of socket--wrenches adapt'- ed for setting and removing rim nutsyot demountable rim wheels. n

The principal object of the: in'ventionisg to provide certain improvements byf-which efficient and readily manipulated 'i100lS, p 21'1 ticularly wrenches, can bev prodlucedj very" In accordance with my inventiom a irod or bar of suitable'le'ngth and cross-section3is split longitudinally for a portion or" "itslength,"and one orboth bifurcations, preterably both, are bent laterally with respect to the remaining portion to form handle or manipulating portions, either or both of. which may be shaped to constitute a tool, and the end of the undivided part of the bar is upset and shaped into a suitable tool head such as a socket wrench.

The invention may be further briefly summarized as consisting in certain novel steps of the improved method which will be described in the specification and set forth in the appended claims.

In the accompanying sheet of drawings showing two different forms of my invention, Fig. 1 is a perspective View of a socket wrench with a screw-driver formedon one of the handles, he same having been, made by my improved process; Fig. 2 is a cross-sectional view substantially along the line 2-2 of Fig. 1;-Fig'. 3 is. a cross-sectional View substantially along the line 3 3 of Fig. 1, this View showing by dotted'lines the originalshape of one of the bifurcations or split portion of the rod or bar; Fig. 4 is a side View of a tool made with a slight modification-in the process; and Fig; 5 isa side View of the same with the tool turned ninety degrees from the position shown in Fig. L.

In carrying out my invention 1 start with a rod or bar 10, ot' the proper length and cross-. :-:ection, the cross-section being; generally round, though this is not essential. The area ot the crosssection oi the pieceend along the piece for. a-distancedepenl this is not esse appear.

will be such as is desirable for forming;"theshank and head of the main to ol tobe formed, and twice the cross-section i the handle or manipulating p'ortions.

Then with a suitable, tool,jtheyp1ece is split .or divided, longitudinally;preferably in the center 1 plane of the: piece, it rom one 7 insupon the desired length of the,.,handle or manipulating portions. In l 1.1 lint Z6 v shown by dotted lines at 10,- .the split portion of} the piece. Then :one or )both. ;otf

the bifurcations or split portions, {thus split or'biturcated portions. areibent gl'aterally into-f alignment to form' ;the handle or manipulating; portions "1,027.; 3 With: :thegtlool. shown in- Fig;1,-the"bifurcated or handlef portions-are bent laterally at ir'ight; anglesii. to the plane of cleavage of the-piece, though.

ntial will subsequently The handle portions lO inay be left in f the shape in which they are iormed when' thepiece is split, in which event, they would I be half round in cross-section, assuming that the originalcross-section of the'piece' is round, but-it desired, by means of suitable dies, the sharp edges of the handle portions may be remoyedby somewhatreshaping these portions, as for example, by giving them a somewhat oval-shape, as shown in Fig. 3 i

One or both the handleiportions may. be shaped to constitute tools, as indicated in" Fig. 1, which shows one of the handle portions p'rovidedxwith vascrew -driver end, shown at 10 I Either before or after the piecefis'split or bifurcated as above explained, the desired tool head will be formed on the shank per t-io'n 10 or unsplit end of the piece. In'this instance, thisendof the piece is provided with, a head 1O in-which is formed a wrench similar, 11-0 tool, with a shank portion 11 on which is formed in the same manner as before, a wrench socket head 11 Likewise, this tool has handle or manipulating portions 11, which as in the first instance are formed by first splitting the piece downward from one end, and by bending the bifurcations thus formed, laterally into alignment, or at right angles to the shank portion. In this instance the handle portions 11 are bent in the plane of cleavage. With this form of the invention the splitting and bending can be readily done in one operation by a pair of cutting and manipulating members which swing scissors-like in opposite directions.

Vith either form of the method above described, tools such as illustrated, can be I produced with great rapidity, finished tools being formed without any machine work as distinguished from that produced by means of dies, but at the same time, the tools are strong, and very serviceable and satisfactory in use. I i I Though I now prefer that the-piece 10 be split longitudinally on the center plane of the same, so that the handle portions are similar, or of equal cross-section, nevertheless the splitting could be done somewhat to one side of the center plane in the event it should be desired that one of the handle portionsbe larger than the other, as might be the case in producing certain combination tools wherein a tool head is formed :on one or on each of the bifurcated portions.

Though the invention has been described chiefly in connection with the production of socket wrenches, the principle of the invention may be used for producing other tools;

comprises longitudinally splitting a bar or rod from one end to'form bifurcations, bending'at least one or the bifurcations laterally, and'forming tool heads on at least one,

of the bifurcations and on the of the rod or bar.

3. The method of making tools which, con

unsplit end sists in splitting a piece longitudinally froln one end for a portion of the length of the piece, bending the bifurcations laterally to form handle portions, and forming atool head on the end of the unsplit portion of the piece. 7 3

In testimony whereof, I hereunto affix my signature.
